MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 1.5KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion FR-F740-S450K-CHT PDF.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation FR-F740-S450K-CHT To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can be omitted FR-F740-S450K-CHT PDF.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large FR-F740-S450K-CHT PDF.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study FR-F740-S450K-CHT Manual .
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V MITSUBISHI Instruction manual.
Power: 0.75kw.
SLD converter rated current: 7.7A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Compatibility with existing models.
Transducer installation size and FR-F700 (P) series of the same, so you do not need to worry about the replacement operation MITSUBISHI Instruction manual.
(rectifier separation type will vary)
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station.
Built in 2 PID arithmetic. In the inverter can be PID control of the motor state at the same time, used in the control of the external machine MITSUBISHI Instruction manual.
No external PID controller is used to control the external machine, so the system cost can be reduced. Power: 30kw.
Voltage: 200V.
There are 100% braking torque output in continuoous regeneration, which can correspond to the continuous regeneration operation of the pipeline control FR-F740-S450K-CHT Instruction manual.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space annd reduce the comprehensive cost FR-F740-S450K-CHT Manual .
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
